摘 要：基于项目的绿色快速建造需求，提出了一种适用于高层工业厂房的免模、免支撑装配整体式框架-现浇剪力墙结构体系（由带牛腿的预制混凝土柱、现浇剪力墙、带牛腿或挑耳的预制叠合梁和预应力空心板构成的体系）。工程应用效果表明：通过在预应力空心板板顶设置后浇叠合层、布置单层双向钢筋，有效提高了楼盖整体性；通过在预应力空心板板端上部开槽，端部布置钢筋桁架或钢筋网，端部浇筑密实，避免了预应力空心板在极端工况下脱落。同时，有限元分析结果表明：通过上述构造措施还可提高楼盖的整体性和抗震性。
Abstract: Based on the green and rapid construction requirements of the project, a temlate-free and support-free assembly monolithic frame-cast-in-place shear wall structure system is proposed suited for high-level factories. The structure system consists of prefabricated columns with corbels, cast-in-place shear walls, laminated beams with corbels or pick ears, and prestressed hollow-core slabs. The engineering application effect shows that laying out the cast-in-place laminated layer and single-layer two-way reinforcements on the top of the hollow-core slab can improve the floor integrity. Sloting at the upper end of the hollow-core slab and placing reinforcements truss or mesh and then pouring concrete densely,can effectively prevent the hollow-core slab falling off. The finite element analysis results show that through these structural measures above can improve the integrity and seismic resistance of the floor.
